BUTTON-HOLE CUTTER.

SPECIFICATION forming part of Letters Patent No. 330,773, dated November17, 1885 Application filed April 6, 1885. Serial No. 161,407. (Model) Toall whom it may concern:

Be it known that I, GEORGE E. OoMBs, a

citizen of the United States of America, re-

siding at Utica, in the county of Oneida and State of New York, haveinvented certain new and useful Improvements in Button- Hole Cutters, ofwhich the following is a specification, reference being had to theaccompanying drawings.

The object of my invention is to provide a button-hole-cutting devicethat may be used in connection with any ordinary shears, that may beaccurately adjusted in position and regulated as to the depth or extentof the cutting movement,and may be readily attached or detached from theshears, as desired.

In the accompanying drawings, Figure 1 represents a side view of ashears having my improvements applied thereto. Fig. 2 is a like viewshowing the side opposite to that shown in Fig. 1. Fig. 3'is an end viewshowing the forward end of the cutter. Figs. 4 and 5 are perspectiveviews of the cutter, showing opposite sides of the same.

A designates the cutter-blade, which is of suitable size for cutting abutton-hole, and is provided with a standard, B, the blade being offsetfrom the standard at a. At the top of blade A is a groove, 0, whichforms a seat for the edge of the upper blade, 0, of the shears. At itsupper end the standard B is bent at right angles over the blade A, asshown, and holds a thumb-screw, b, which passes through a threadedaperture in vertical position to bear against the back of theshear-blade 0. Another screw, d, passes through standard B in horizontalposition to bear against the side of blade 0 for adjusting the device inproper position. By these means the device may be firmly clamped to theshear blade and also accurately adjusted in relative position.

D indicates a slide-gage for regulating the depth or extent of thecutting movement, having a seat or holder, 8, formed for it adjacent tothe lower end of the standard 13. The gage, which is usually made ofbrass, has an enlargement or knob at its lower end for contact with thelower blade of the shears to stop the cutting movement, and also has onone side a number of projections or stops, 6, for engagement with anotch, f, in the holder 8. There is a Vertical-slot or opening, 9, inthe seat or holder 8, and when the gage is turned so that the stopse arein line with the slot it may be moved up or down freely, be fixed at anydesired point, by turning it so that one of the stops 6 enters thenotchf.

The desired length of button-hole is obtained by moving the gage D inthe holder to the proper point, and then turning it so that a projectione enters and rests in the notch.

The device described forms a convenient attachment for use in connectionwith a shears, and may be readily attached and adjusted and removed asdesired.

Having described my invention, I claim- 1. In a button-hole cuttingdevice adapted for attachment to shears, in combination with acutter-blade, a clamping device having a vertical screw, b, a groove forreceiving the edge of the shear-blade, and an adjustingscrew to pressagainst the side of the shearblade, substantially as and for the purposedescribed.

2. In combination with the cutter-blade provided with a clamping device,substantially as shown, a sliding gage provided with projections e, andthe holders, having anotch, f, substantially as shown and described.

In testimony that I claim the foregoing as my own I affiX my signaturein presence of two witnesses.
